The Dam Stands for Damiana, a medicinal herb used for thousands of years to relieve tension, calm anxiety, and improve blood flow. Prized by the Guaycura, Aztecs and Mayans, Damiana is considered a National Treasure in Mexico to this day. The original margarita contained Damiana, and so did the precursor to a certain famous Coca drink. ThatDamTea is brewed with whole Damiana leaf, and absolutely nothing artificial. But seriously, don’t bring this to Louisiana, it is actually illegal there.
